This site, probably NSFW, makes use of the datastore (for the thumbnails) and it's now much faster, it's a pity we can't compare speeds with the old latency. http://wallres.saiswa.com/?tags=girls&pagina=23

A SFW website with a lot of images too.. yes, considerably faster.. http://my.educonsole.com/free-educational-games-for-kids/ide...

(By the way, the above site was my gift for my son on his fourth birthday)

It's amazing the difference low latency can make when dealing with lots of small images.

Our app (http://gri.pe) feels a lot snappier after this latest bit of datastore maintenance. We've been using as much memcache as possible to avoid datastore access because prior to this maintenance, datastore access was spiky and even the simplest of queries had a small chance of timing out.

I can say for sure that some of our datastore-heavy cron jobs were taking > 200ms, but are around 70ms now.

It's a shame that the stats for > 12hrs ago seem to have been wiped. I bet we'd be seeing a marked improvement on our ms/request stat.

Earlier quoted context omitted.

Put, Update and Delete are much faster too.

looks like they took a 1hr write outage at deployment time, so presumably a fairly beefy change under the hood.

Most of the datastore maintenance windows are about an hour long. Previous ones have even gone two hours.

Not me. And, even if I wanted to, I can't. Also, I guess Google folks would post about the performance boost later.

Ok, please excuse me.

In either case - from the HN guidelines: "Resist complaining about being downmodded. It never does any good, and it makes boring reading."

Looking at the error rates, I wonder what happened at around 12pm? (Screenshots: http://grab.by/7gJ4 http://grab.by/7gJ5 http://grab.by/7gJh )

From the maintenances mailing list:

The maintenance work has been completed. The datastore was in a read-only period between 12:02-12:45 for a total of 43 minutes. Some users reported two periods of 500 errors unrelated to datastore writes, but these issues should no longer be occurring.

My dinky app dropped from 60ms/request to 20ms/request, but over the next 3 hours crept up more or less linearly to about 30ms/request.
